Two women attack a man and smudge fake poisonous substance on his face during an anti-terrorism drill at a subway station in Goyang, just north of Seoul, on March 13, 2017. This particular exercise mimicked the attack on Kim Jong-nam, the half brother of North Korea's top leader Kim Jong-un, who was killed in the same manner at Malaysia's airport late February.
